Overview

The SQUARE D 9013FHG59J52M1X is a diaphragm-actuated air compressor pressure switch designed to control an electrically driven air compressor within a power circuit. The switch cuts out at a fixed 125 PSI setting and features an adjustable cut-out range of 100 to 200 PSI, with a non-adjustable differential of 40 PSI. Electrical connections are screw terminal style with two 2-pole normally closed contacts that open on rising pressure. The cut-out threshold adjusts via a screw nut. Installed by licensed electricians or HVAC-R technicians, this switch suits compressor systems requiring reliable automated pressure control. This pressure switch is rated for use with higher-horsepower motors of 2 HP or greater, making it appropriate for commercial-grade or heavy-duty residential air compressor installations. The 1/4 inch NPT external fluid connection provides a standard fitting interface for integration into existing compressor plumbing. The switch includes a 2-way pressure release valve and a maintained manual cut-out lever with auto and off positions, supporting controlled startup and manual override scenarios common in shop and industrial compressor setups.
